Location: Ilha Marajo in the Mouth
of the Amazon is the size of Switzerland.

Mission Statement:

There are three species of anacondas, the wide-spread
common green anaconda (Eunectes murinus), which occurs throughout
the Amazonian and Orinoco river systems, the yellow anaconda (E.notaeus)
from southern Brazil, Paraguay and northern Argentina, and the rare
and little known de Schauensees anaconda from the Ilha Marajo
in the mouth of the Amazon. Mark has always wanted to visit the
huge island of Marajo, an island the size of Switzerland and the
largest island in the Amazon river mouth where the opposite banks
are 200 miles apart or the distance from London to Paris. It has
been his long term aim to capture one of these poorly documented
anacondas and compare it with a green anaconda from the same area.
How and why do they differ ? How can two species of anaconda co-exist
in the same flooded savannas and water courses ? And how big can
they grow ?

A close view of a De Schauensee's
anaconda (Eunectes deschauenseei), the head is similar to that of
the yellow anaconda (E.notaeus).
